The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Reward has a residual impact on target selection in visual search, but not on the suppression of distractors (2011, background): “…the rapid detection and localization of target features (e.g., Hopf, Boelmans, Schoenfeld, Luck, & Heinze, 2004), which is followed by the suppression of distractors such that detailed target features can be resolved (e.g., Desimone & Duncan, 1995; Luck et al., 1997; see also Hickey et al., 2009).”
ERP Components: The Ups and Downs of Brainwave Recordings (2011, background): “However, later evidence demonstrated that the N2pc does not refl ect fi ltering of the distractors per se, instead refl ecting operations that must be applied to the attended object itself when distractors are present (Hickey et al., 2009 ).”
Visual search: a retrospective. (2011, background): “…electrophysiology studies have also found an ERP component (Ptc, a positive component with a more temporal scalp distribution than the N2pc) that might be related to the suppression of the processing of distractors (Hickey, Di Lollo, & McDonald, 2009; Hilimire, Mounts, Parks, & Corballis, 2011).”
Modulation of rhythmic visual stimulation on left–right attentional asymmetry (2023, background): “, N2 posterior contralateral (N2pc) (Luck and Hillyard, 1994; Fuggetta and Duke, 2017) and distractor positivity (Pd) components (Hickey et al., 2009; Suarez-Suarez et al., 2019).”
